Gore calls for 350 goal at Poznan

Following up on Betsy's blog, Bill McKibben delivers some great news from Poznan:

Giving the climactic speech at the Poznan global warming conference, Gore set the new bottom line for action on global warming, right where we've been suggesting: 350 parts per million. The old goal of 450 parts per million is "inadequate," he said. We "need to toughen that goal to 350 parts per million."

The line, which drew the longest applause of the day, was a remarkable repudiation of established targets that have driven the climate debate for more than a decade. Now the world's leading scientific authority on global warming and the world's leading political authority on global warming have said the same thing: 350 is the target we have to hit. Let's get to it.

Here's some video of the concluding portion of Gore's speech (h/t to oneclimate.net), and a fuller account of the speech.
